The reality is – we have no real idea what chemicals will be added to our water … Chlorine tablets containing the necessary dosage for drinking water disinfection can be purchased in a commercially prepared form. Guidelines for Drinking-water Quality, 4th Edition, Incorporating the 1st Addendum. Allowable chlorine levels in drinking water, called maximum residual disinfectant levels (up to 4 parts per million), pose “no known or expected health risk [including] an adequate margin of safety.” 2 WHO. However, obtaining our required chlorine levels through drinking water has been shown to be quite dangerous. The presence of free chlorine (also known as chlorine residual, free chlorine residual, residual chlorine) in drinking water indicates that: 1) a sufficient amount of chlorine was added initially to the water to inactivate the bacteria and some viruses that cause diarrheal disease; and, 2) the water is protected from recontamination during storage. The human body does require chlorine as it is one of the minerals our body is made out of. More of a concern is the long term risk of cancer due to chronic exposure to chlorinated water. These tablets are available from drug and sporting goods stores and should be used as stated in the instructions. The WHO recommended level for drinkable water is 0.2–0.5 ppm minimum (14, 15) and 2–5 ppm maximum (12, 13) free chlorine. 2017. P. 173. You originally asked the question – how to remove chlorine from water? The allowable chlorine levels in drinking water (up to 4 parts per million) pose “no known or expected health risk [including] an adequate margin of safety.” Only chlorine based disinfectants can provide lasting protection from waterborne diseases throughout the distribution system from treatment plant to the consumer’s tap. It is desirable to maintain a residual concentration of free chlorine in drinking water to prevent the proliferation of pathogenic microorganisms. Most drinking water has a small amount of chlorine added to it as a preventative measure against the spread of disease and dangerous pathogens. Drinking chlorine water can have a range of effects on the body, ranging from positive to negative. This is mainly due to the trihalomethanes and other disinfection by-products, which are by-products of chlorination. – but the issues with drinking water go much wider. How to Remove Chlorine from Water The Solution Is Effective Filtering. Estimated total exposure and relative contribution of drinking-water If a daily water consumption of 2 litres and an average chloride level in drinking-water of 10 mg/litre are assumed, the average daily intake of chloride from drinking-water would be approximately 20 mg per person (4), but a figure of approximately 100 mg/day has also been In drinking water, the concentration of chlorine is usually very low and is thus not a concern in acute exposure.
